The links below take one through the four clips that, together, make up almost all the full Chronicle episode, "Beyond the Cure", which aired on May 17th. Unfortunately, each clip is preceded by a short commercial....but worth the wait.
Part 1 of 4: Opening Segment (6m16s)
Part 2 of 4: New Treatments (4m41s)
Part 3 of 4: Stuck in the Middle (6m23s)
Part 4 of 4: Lasting Relationships
